在 C# 中使用 Java 类

Using Java-classes with C#

提问by Burkhard

I have a project written in Java (>1.5).

我有一个用 Java (>1.5) 编写的项目。

Is it possible to write parts of the project with C#?
For instance the GUI and calling the methods and instantiate the classes written in java?

If yes, how?

There is something called Java Language Conversion Assistantfor .NET. You can convert your Java classes to c# and start coding.

有一种叫做.NET 的Java 语言转换助手。您可以将 Java 类转换为 c# 并开始编码。

There is also something called JNBridge(not free).

还有一种叫做JNBridge（不是免费的）的东西。

Not without something like ikvm- or using web services etc to communicate between the two sides. Basically it's likely to be much more work than either rewriting your existing project code in C# or writing the GUI in Java.

不是没有像ikvm这样的东西- 或者使用网络服务等在双方之间进行通信。基本上，它可能比用 C# 重写现有项目代码或用 Java 编写 GUI 要多得多。

It seems like my solution is very limited. and apply only to specific version of java.

看来我的解决方案非常有限。并且仅适用于特定版本的 java。

I probably will stay with old good C :) Can't imagine how to work without shared libraries :)

我可能会继续使用旧的好 C :) 无法想象没有共享库如何工作 :)

This documentexplain how to create a dll from java and use it in C code. I'm not C# or java expert but i'm sure that you can load external dll's in C# as well. So not a complete solution but good starting point, IMHO. Generally dll it's a perfect way to mixing languages.

本文档解释了如何从 java 创建一个 dll 并在 C 代码中使用它。我不是 C# 或 Java 专家，但我确信您也可以在 C# 中加载外部 dll。所以不是一个完整的解决方案，而是一个好的起点，恕我直言。通常 dll 是混合语言的完美方式。

In simple way you can pack your java classes to jar file then In C# use Processclass for execute and map IO stream

以简单的方式，您可以将 java 类打包到 jar 文件中，然后在 C# 中使用Process类执行和映射 IO 流

I did some research on this a few years ago (2005 I believe) and I liked JNBridgePro as the best third party product to do this. Check it out here http://www.jnbridge.com/

几年前我对此做了一些研究（我相信是 2005 年），我喜欢 JNBridgePro 作为最好的第三方产品。在这里查看http://www.jnbridge.com/

Good luck!
